With the observed earthquake sequence data and the waveform data in the hypocenter region of the M5.1 earthquake that hit Dengta County in Liaoning on 23rd January, 2013, this study calculated the amplitude spectrum correlation coefficient before and after the M5.1 earthquake, and performed data clustering. Meanwhile, through comparing the focal mechanism of the mainshock and the maximum foreshock, this study explored whether the Dengta M5.1 Earthquake had foreshocks, and found that the foreshocks of Dengta earthquake had a consistent focal mechanism.
